QONDUCTING-CONDUIT FOR VEI-HCLES.

T all whom it may concern:

' Be it known that I, FRANCIS M. BRINCKER' now, a citizen ofv the United States, residfollowing is a specification.

My invention relates to electrically-propelled vehicles; and-it consists in the novel construction of certain parts and combinations ofparts pointed out in the claims concluding this s ecification.

In electrically propelled vehicles endeavors have constantly been made toward the solution of' the problem of reducing the weight of the equipment. Such endeavors have resulted in the construction of certain devices whereby air maybe conducted into and circulated through the motors, rheostats, etc., in order to cool the same, such air becoming heated in the operation and being directly discharged from the motor outlets, or further utilized for heating the car in cold weather. e

A device of the above general character is described and shown in Letters Patent of the United States to Lewis B. .Stilwell, No. 811,967; dated February 6, 1906, and the purpose'of my present invention is to provide im roved forms of connections between the various conduits through which the air passes in its travel to and from the motors,

- rheostats, etc.', after it has passed'through or before it is discharged into'the passages in the body of the car; such connections having a universal movement mrelation to the car body and the motors, rheostats, "etc.

By reason of the various movements, vertical, horizontal, and swivel, rendered pos sible by reason of the improved joints, my invention is especially suitable for use on cars and trucks operating on curves of short radius where the use of ordinary connections is extremelydillicult In the accompanying drawings, Figure 1 is a side view-of a car showing the general .;ystem of air conduits, connections and in closed motors. Fig. 2 is a longitudinal plan view partly in section of the car body, floor, and. sills, showing a general plan of air distribution. Fig. 3 is an end. elevation showing the car body bolster resting om the truck with half of a motor removed. Fig. 4 is av plan of the motors and. car body bolster showing in section the connection Specification of Letters Patent. Application filed Mai-eh 12.

between a motor and .a horizontal air conduit. Fig. 5 is a sectional view in end elevation-of the car body bolster resting on the truck and connected to vertical air conduits. Fig. 6 is a view in side elevation, with a modishown insection. Fig. 7 is a sectional .view in end elevation of a modified form of connected vertical conduits. Fig. 8 is a sectional plan view of the construction shown in Fig. 7.

Similar characters of reference indicate same or corresponding parts in the several figures.

I will now describe the various structures shown in the accompanying drawings, which presentpreferred by me but it will be understood that various modifications and changes may be made without departing from the spirit of my invention and without exceeding the scope ofthe claims concluding this specification.

Referring to Fig. 1, the body of the car is shown in dotted lines.

m, m are motors suitably inclosed and connected by air conduits.

lengthwise of the car between the floor'and bottom ceiling thereof, being provided at one end with a broad mouth I) and at the other connected with the air passage in the plates or boxes 1 attached to the car body; the movement of the car is considered as being toward the left. Another form of air in-take is shown as 292 running lengthwise between the roof and upper ceiling of the car and provided with a mouth b its connection with the car body bolster being by means the side wall of the car.

Referring to'Fig. 2 the motors m, and m? are shown in dotted lines with the connections between them and suitable plates or boxes 1, which are attached to the car body and have apertures for the passage of air, there also being apertures in the lower ceiling J of the car above 1. In the preferred form as shown two air conduits C and D are formed by the sills F, the lower ceiling J, the

and H, at the center line of the car. The left'end of C (not here shown) is provided with an opening for the admission of air and the car being in motion toward the left the.

air enters in a stream which takes the direcfied form of universally movable connections drawings illustrate forms of my invention at p is the conduit form-take of air, running floor H, and a partition E placed between J l of conduit running vertically in or near tion of the lower series of arrows and enters l the motors through 1 and its connections. Having been forced through the motors, by reason of pressure caused by the movement of the car, the air escapes through the corresponding motor connections and box 1 on the other side of the center line of the car into the air conduit D, taking the direction shown by the upper series of arrows; thence, by any suitable means, the air may be conducted through the car in order to heat the same, and be discharged through an opening, such as S, placed in the roof of the car, or the air after leaving the motors may be directly discharged without so passing through the car.

Referring to Fig. 3 the car body bolster is shown resting on the truck with half of the motor at removed and the connections between the air passage C and the motor be shown in section.

F, F indicate the sills of the car body, H the floor and J the lower ceiling thereof; E indicates a partition between the floor and said ceiling at the center line of the car.

C and D indicate the air passages thus formed, there being suitable openings in the lower ceiling J at the point at which it is desired to connect the passages C and D with the conduits to the motors m and m Members 1 are suitable plates or boxes attached to the car'body, each having an aperture 0 for the passage of air, and having suitable flanges e which are in contact with flanges f of members 2 and are retained in such contact, in order to form a tight joint, by means. of sprin s such as 1 r and y, y, shown in Fig. 5, or by other suitable means. Members 2 are made a snug fit for members 3, which in turn are attached either to the truck bolster or to the truck frame as may be desired. The air being forced in through C, passes through the passages formed by members 1, 2.and 3, and enters the motor m through other members 4 and 5 forming the passage 0, as is shown in Fig. 4, and the motor m by a similar passage. Having circulated through the motors the air passes through a like series of passages formed by another series of members 5, 4, 3, 2, and 1, on the other side of the center line of the car and enterin D is conducted to a point of discharge. y the combination of these three members 1, 2 and 3, as shown, the following motions between the car body and the truck have been rovided for. The flanged surfaces of mem ers 1 and 2 are free to move in relation to each other in a horizontal lane, cons ulently the truck can swivel un er the car body without breaking the joint between 1 and 2. Members 2 and 3 are free in a vertical plane, consequently any variation in height between car body. and truck bolster is )rovidcd for.

Referring to ig. 4, there is shown a plan view of the motors and car body bolstervv'itb be preferred in somev cases.

one-half of one set of the members 1, 2 and 3 cut away and the passage 0 mto the motor m shown 111 section. Member 3 is provided with a projection in a horizontal plane adapted -to receive a member 4 with a sliding joint; member 4 is provided with flanges, (I and b, the latter being in contact with a flange 0 on a member 5 in such a manner as to secure a tight joint between 4 and 5; such contact is maintained by means of springs 00, cc, which rest on flanges d projecting from the wall of member 3 and press against flanges a of member 4, or by other suitable means. Member 5 is suitably attached to the motor at a convenient point,'and is provided with an aperture for the passage of air to or from the motor. By this combination of the horizontal projection on member 3, and the members 4 and 5, as shown, motion in a horizontal plane between the truck bolster and the truck frame, on which the motors rest, is provided for.

Referring to Fig. 5, there is shown, in sectional end elevation, a simplified view of the connections of the vertical conduits between the air'passages C and D and the motors m and 171?, which passages have heretofore been described in connection with Fig. 3. The members 2 are shown as held in contact with members 1 by means of the springs r, r, and y, y, which press against inturned flanges g of members 2 and rest upon flanges h which project from the inner wall of member 3.

Referring to Fig. 6, there is shown in sectional side elevation one of the continuous passages between C and D, the air passages in the car body, and the motors m, m", with a modified arrangement of the springs as and-'y, which preserve the close contact between members 1 and 2 and members 4 and 5, re.- spectively. By making a sufficiently tight joint between members 2 and 3 and 3and 4 respectively, the spring members may be dispensed with, if desired, but their use may Considering the air supply as being attached to the passa e C, we lave a passage from the car bot through the openings in members 1, 2, 3. and 4 and 5 to the motors m, and m, through which the air can pass by various ways to the'other side of the motors and thence pass out through other sets of members 5, 4, 3, :2 and 1, to passage D to be distributed as desired. It is obvious that the direction air may be varied and that both sets of =.cm hers may be used to convey air to the motors m and m and the air be allowed to escape at once from the motor outlets if so desired. As may be clearly seen by reference to Fig. 6, the motions are provided for, comprising the swivel motion between members 1 and 2, the vertical motion between members 2 and 3, and the horizontal motion between the horizontal projections3and the members 4. I h ave thus provided a continuous passage betruck center plate A.as its center, the air passing from C through the members 1, 2, and 3, as heretofo e described. Such a construction may be rther modified in order to provide for the passage of the air through the center plate casting A, itself, and thence into the' bolster, but the construction as shown is preferred.

Referring to Fig. 8, there is shown a sec tional .plan view of the construction described in connectionwith Fig. 7. a

In the figures which have been described in the foregoing portions of this specification the various members; 1, 3, and 5 have been shown res ectively as attached to the car body, the v olster and the motors, but these.

members ma be cast or formed as integral portions of t e car body, bolster or motors, as may be found advantageous in some constructions. This maybe illustrated in the case of member 3 which is shown as partly within the truck bolster, but which may be constructed so as to form an integral part of the bolster.
